If you’ve ever taken a ride in any late model vehicle recently, you’ll already aware of its superior handling, driving, and ride characteristics. It’s amazing what 30 years of technology in the chassis department can produce. Bumps, bends, and nearly any fold in the road surface are soaked up with ease. While we all love hauling around in our project vehicle, to a certain extent, its ride characteristics are merely tolerated. Not to mention, none were well known for their spirited, high performance driving either.

Since all of our muscle car favorites from the ’60s-70s all came equipped with a live rear axle, aside from adding a different set of leaf springs or shock and spring assembly, there really wasn’t a whole lot on the table as far as rear suspension upgrades were concerned.

Don’t get us wrong, upgrades like an aftermarket set of springs and shocks can do wonders on these old timers. However, if you want a modern ride like your late-model favorite with the ability to have it all completely bolt-in, Heidts Hot Rod & Muscle Car Parts has those bases covered. Heidts is no stranger to the game either; effortlessly supplying the aftermarket with cutting-edge suspension and chassis parts for twenty-five years!

Heidts is stepping up and is currently producing an all new ’64 1/2- 70 Ford Mustang Independent Rear Suspension (IRS) system. Guess what? It’s all completely bolt-in, too. Hedits’ IRS is taking the benefits of its PRO-G Subframe and will transform your Mustang into a true Autocross competitor.

Additionally, no matter which mill you’ve decided to power your ride, Heidts has designed this IRS system to handle up to 600hp. Heidts has truly desinged a bolt-in, hub-to-hub IRS system that will make your Mustang the hottest ride in town.
